dnf.exceptions.error some packages from local repository have incorrect checksum

I am trying to install redhat (rhel8) in virtualBox 6.1 on a windows 10 64 bit Home edition machine. I verified the checksum of the iso file after download and its correct (I compared the checksum against another friend iso file who is able to install properly), still I am getting exception like dnf.exceptions.error some packages from local repository have incorrect checksum enter image description here

I even tried to run troubleshooting, but it raise exceptin like failed to start media check on /dev/sr0 virtualbox I have downloaded the iso files from multiple places and every time it gives me the same exception. Any help is highly aprreciated.

Solution

  • Finally I found the reason for the above error.

    Virtual Box uses virtualization to run multiple Operating Systems and in one system (let's say a windows machine) only one of the application will be allowed to use system virtualization capability. So we have to disable any manual virtualization if performed in the system.

    So we can disable virtualization by following ways:

    • Search for “Turn Windows features on or off” in the Start menu, hit the Enter key to open the Windows Features window. Here, scroll down to Hyper-V and disable it by clearing checkbox next to it. Then click OK

    • Disable Hyper-V by using command.

    Press Windows logo key + X, then hit A to run Command Prompt as administrator. In Command Prompt window, type

    bcdedit /set hypervisorlaunchtype off

    and hit Enter key to execute this command. enter image description here

    Finally restart system.
